Astronomy Picture of the Day (or APOD) has just released new 2015 calendars filled with breathtaking images of Earth and space. There are currently eight calendars available: Galaxies, General, Skyscapes, Moons and Planets, Star Clusters, Spaceflight, Sun, and Weather & Volcanoes. The calendars can be downloaded for free from the Friends of APOD website, though donations are welcome from anyone willing to help. Printed copies are also now available for a fee.
Weather & Volcanoes, in our opinion, is the best calendar. From beautiful iridescent clouds photographed in 2009 from the Himalayan Mountains in Nepal, behind the 6,600-meter peak named Thamserku, to lightning bolts illuminating the ash pouring out of the Eyjafjallajkull volcano, you’ll find it all here. Each photograph serves as a reminder of Mother Nature’s incredible power and beauty, as well as the world in which we live.
